Abdominal Aortic Aneurysm

Understanding Abdominal Aortic Aneurysm (AAA)

Abdominal Aortic Aneurysm (AAA) refers to a potentially serious condition where the large blood vessel that supplies blood to the abdomen, pelvis, and legs—the abdominal aorta—becomes enlarged and weakened.

This enlargement can cause the artery wall to bulge outward like a balloon. AAA is often asymptomatic in its early stages but can pose significant health risks if it grows larger or ruptures.

Side Effects of Abdominal Aortic Aneurysm

The most concerning side effect of AAA is the risk of rupture. If an aneurysm ruptures, it can lead to severe internal bleeding, which is a life-threatening emergency.

Other potential complications include blood clot formation within the aneurysm (thrombus), which can also increase the risk of rupture, and compression of nearby structures leading to pain or other symptoms.

Diagnosis of Abdominal Aortic Aneurysm

Abdominal Aortic Aneurysm is commonly diagnosed through imaging tests such as ultrasound, CT scan, or MRI. These tests can accurately measure the size of the aneurysm and assess its location and shape.

Early detection through routine screening is crucial because smaller aneurysms are generally less likely to rupture and can be monitored more conservatively.

Treatment Options for Abdominal Aortic Aneurysm

Treatment options for Abdominal Aortic Aneurysm depend on several factors including the size of the aneurysm, its growth rate, and the overall health of the patient:

• Watchful Waiting (Monitoring): For smaller aneurysms that are not causing symptoms and are below a certain size threshold, regular monitoring through imaging tests may be recommended to track any changes.
• Surgery: If the aneurysm is large or growing rapidly, or if it causes symptoms, surgical intervention may be necessary. The most common surgical approach is aneurysm repair, which can involve:
  
• Open Surgery: Involves replacing the weakened portion of the aorta with a synthetic graft.
• Endovascular Repair: A less invasive procedure where a stent graft is inserted through small incisions in the groin and guided to the site of the aneurysm to reinforce the weakened artery wall.
• Medication: In some cases, medications to control blood pressure or cholesterol may be prescribed to reduce the risk of aneurysm growth and complications.
